The one-time performance of a credit card shall not exceed 50% of the cardholder's credit card limit. If the cardholder's credit card limit is 10000 yuan, then the maximum credit card limit can only be 5000 yuan.

However, it should be noted that credit card withdrawal requires a certain withdrawal fee, and five ten thousandths of cash interest will be charged every day. For example, if the cardholder borrows 10000 yuan, he needs to pay 5 yuan interest to the bank every day.
